Discovering Wireless Sensor Networks: Applications in Structural Health Monitoring, Part 2

Author: Dr. Masoud Agah

This curriculum module is part of a set of four curriculum modules. The curriculum module can be adapted to be used alone, or used as part of the set. In this set of projects, students learn about the importance of monitoring stresses on bridges and other civil infrastructure, and about how public safety can be improved by using wireless sensor networks for continuous structural health monitoring. This curriculum module, the second in the set, introduces topics in micro-electrical-mechanical systems (MEMS), microsystems, and sensors. The students learn how MEMS technology has impacted a wide variety of products and applications, including airbags for automobiles, printheads, Wii controllers, and tools for analysis and sensing in medicine, biology and chemistry. In the lab, they use resistive sensor read-out circuitry developed in the first curriculum module, along with a resistive strain gage, to measure strain as a ruler is deflected. In the process, the students learn about the relationship between the digital signal captured and the physical quantity being sensed, and the factors that influence that relationship.
